> No, when you asked Nintendo to manufacture you a run of cartridges, you paid for them whether they sold or not. You took that risk.

That was exactly my point. Distributors like EA or Activision will charge you because they took that risk. It wasn't Nintendo or SEGA.

Valve is like Activision, not like Nintendo.

Nintendo charged you because they lost money on the consoles. Valve looses no money.
